Halfway through I was ready to give this 3 or 4 stars as simply a good thriller with solid characterization and plotting, but then a couple of sub-plots rose up unexpectedly and mugged me and turned this from just good to exceptional. So if you think this is just about saving Larry Durrant, think again! From then on it was a breathless nail-biter. The read has a nice feel to it because 70% takes place with a cat and mouse game outside the prison walls. There was enough inside the prison to give the dour atmosphere, but not so that you got bogged down there. It also avoided being weighed down with endless death penalty statutes, which I felt both The Chamber and Conviction suffered from. What on top made this read different was that the prisoner himself doesn't even know whether he comitted the murder or not - so you as the reader go all the way through thinking did he, didn't he? And the piecing together of Larry's fractured psyche around his life at the time of the murder 11 years ago, with all the time the clock ticking rapidly towards his death - is pure genius! For an emotional and exciting thrill-ride, an absolute must read.
